Bone TB or something else?

Diagnosis of MRI done on 2nd Apr 10 : MR imaging of Left knee joint reveals a large irregular lobulated thick walled lesion showing central fluid intensity noted in the metaepiphyseal region of the lower femur causing mild thinning of the anterior cortex and small defect in the posterior cortex with extension into the adjacent soft tissue posterior to the femur.

Note also made of edema and fat stranding in the soft tissue surrounding the lesion as well as lower metaphyseal region of femur.

Findings suggest Differential of infective etiology with the remote possibility of mitotic lesion.

As compared to previous MRI dated 27th Oct 09, Perilesional marrow edema and joint effusion appears to have reduced while the collection/extension in the posterior soft tissue appears to have increased.

Hello.Welcome to HCM forum.Once the biopsy has revealed a positive mycobacterium tuberculosis you should not be in doubt.Go for complete course of tuberculosis.You will be alright.Get the MRI repeated after the full course of antirubercular medicines.Thanks and good luck.
